To release the core, the head of the pin F is drawn outward, permitting the core to freely drop by gravity from the socket A.

From the foregoing description the operation of the wrench will be clearly apparent, as when the handle is to be locked for turning in any direction the ring is shifted to carry the opposite pawl out of engagement with the ratchet, and this simple an d efficient construction permits the direction of movement to be quickly changed, so that the wrench can he used for turning a nut or bolt in either direction in the quickest possible manner. It will therefore be seen that the wrench is particularly adapted for use in machinery and other places where the ordinary handle of the wrench can not he operated, as the socket. may be inserted into contact with the nut or bolt and the same easily rotated, even in positions where the ordinary wrench cannot be used. With the pawls in the poU sition shown in Figy l itwill be seen that the handle may be turned in one direction without affecting the ratchet or wrench-socket, while in the reverse movement the socket. will be turned, thus permitting the use of the handle in positions where a full revolution could not he made.

It will be obvious that changes may he made in the details of construction and configuration without departing from the spirit`of the invention as deiined hy the appended @We Having described my invention, w it I claim as new, and desire to secure by Letters Patent, is-

l. A socletwrench comprising a shank having,r a ratchet-wheel thereon, a handle provided with oppositely-disposed pawls or dogs adapted to engage said ratchet, and means carried by said handle having a projection extending' between the pawls for holding one of said pawls out of operative position; substantially as specified.

2. A socket-wrench comprising a shank having` a ratehet-wheel thereon, a handle provided with oppositely-disposed pawls or dogs adapted to engage said ratchet, a ring surroundingY said handle, and a pin extending inward lfrom said ring and'lying between said pa wls, whereby a rotary movement of the rin 9; will throw one of said pawls out of operative position; substantially as specified.

3. A socket-wrench comprising a shank carrying at one end a ratchet-wheel, oppo sitely-disposed pivoted pawls,a spring for normally holdingr said pawls iu engagement with said ratchet-wheel, a ring mounted upon said handle, and an inward projection from said ring adapted to engage and move one of said pawls ontof operative position; substantially as specied.

In testimony whereof I affix my signature in presence of two witnesses.
